NUMBERING DEVICE.

To all whom it may concern:

Be it known that I, EDWARD citizen of the United States, residing atMinneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain new and. useful Improvements in Numbering Devices; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide a simple and highly efficientmarking device, especially adapted for use in numbering or otherwisemarking storm sash, screens and windows, but adapted, nevertheless, formore general use.

To the above ends, the invention consists of the novel devices andcombination of devices hereinafter described and defined in the claims.

The invention involves a multiplicity of socalled index plates providedwith numer als or other characters adapted to be alined or assembled indifferent ways to indicate different numbers or various differentmarkings, and which plates, when assembled, are secured againstaccidental rotation or other movement which will change the setindication thereof.

The preferred form of the improved marking device is indicated in theaccompanying drawings, wherein likecharacters indicate like partsthroughout the several views. I

Referring to the drawings, Figure 1 is a plan view of the improveddevice, with some parts broken away; Fig. 2 is a plan View of the largeror outside index plate removed from working position; Fig. 3 is a viewpartly in edge elevation and partly in section on the line 00 m of Fig.2; Fig. l is a section taken on the line 00 00* of Fig. 1, some partsbeing broken away; Fig. 5 is an enlarged View, partly in elevation andpartly in section, on the line 00 m of Fig. 1, showing the improveddevice applied in Working A. CRosBY, a

. is a section taken on the line m as of Fig. 6.

The larger or outside index plate a is in the form of a decagon and itsten flat surfaces are slightly beveled or incliaed and each is markedwith one of the digits one to nine, and zero, these characters, asshown,

stated that this has been the numerals on the said large as also beunderstood that when the Patented July 5,1910. Serial No. 511,906.

being formed by upwardly stamped characters b. At its angular inneredge, the said plate a is provided with an angular inwardly offset ledgec that terminates in the plane of the outer edge of the said plate a, sothat it is adapted to be pressed against the flat surface of a stormsash or screen frame or similar body. The inner or smaller index plate,in this preferred construction, also has ten peripheral angles adaptingit to fit quite closely within the ten-sided seat formed within theplate a just outward of its ledge 0. Preferably, this inner plate 7 ismade in the form of a double fold, the two folds being connected only atone of the ten angular edges of said plate. The numerals g are formed ormarked in part on one side and in part on the other side of the saidtwofold plate f and, as shown, in the drawings, they are formed bystamping and pressing the same outward from the body of the said plate.In the preferred arrangement, one side of the said plate 7 is providedwith the numerals l, 2, 3, and a and with a blank space between thenumerals 1 and I, and the other side of said plate is formed with thenumerals 5, 6, 7 8 and 9. By reference to Fig. 6 it will be noted thatthe numerals 1, 2, 3 and 4 are alined with alternate angular sides ofthe said plate 7, and it may be here done in order that plate f may beas those on the plate a, and without crowding the numerals.

From what has been said, it will, of course, be understood that thetwo-fold plate 7 is reversible to present the desired numeral or blankspace in alinement with the desired numeral of the plate a necessary togive the required marking of indication. It will plate f is seatedwithin the plate a, it will be interlocked therewith, that is, will bepositively held against rotation in respect thereto. This locking of thetwo plates against rotation, however, may be provided for in a greatmany different ways, it being necessary, of course, in all of suchconstructions, that the two plates be capable of adjustment to aline anyof the characters thereof and that the two plates be secured againstrotation when put together or when the device is complete.

The two index plates, in the preferred form of the device, are containedwithin a shield or cover h, the periphery of which is seams formed witha marginal serrated or toothed flange 70 having ten angles and ten sidesadapted to closely fit the ten angles of the plate a and thus hold thelatter against rotation. The teeth 7: are adapted to be pressed into thewood of the frame 3 as shown in Fig. 5, and thereby securely hold thesaid shield against rotation. The shield is provided with a radial slotor sight opening m, the sides and inner extremity of which are turnedinward so that they closely engage the faces of the index plates at andf and thereby prevent the entrance of dirt into the shield. The numeralsof the plates or and f, which are to give the desired marking number,are exposed through the sight opening m, as shown in Fig. 1. A screw ppassed through an axial perforation in the shield h and through an axialperforation t in the two-fold index plate f and screwed into the frame yserves to secure all of the parts of the device together and to theframe A nail or other device might be used instead of the screw, but thescrew gives the best results.

WVhen the device is applied as shown in Fig. 5, it projects but veryslightly (in practice considerably less than shown in the drawings)above the face of the frame y and has no sharp angle exposed at itsexterior.

The index plates and the shield are all preferably stamped from thinsheet metal and, hence, it may be made at very small cost.

The device designed as shown is adapted to be set to indicate any numberfrom 1 to 99, and this will be found sufficient range for most purposes.Where a larger range is desired, a large number of index plates will beprovided. For instance, by adding a third index plate any number up to999 could be indicated.

This device provides, at very small cost; a standard or uniformstructure which is capable of being set to properly number or mark stormsash, screens, windows and Various other things, thus making itunnecessary for a merchant to carry a variety or assortment of devicesfor the purpose for which this device is intended.

While numerals will be usually employed in the index plates, othercharacters may, when desired, be employed, and these characters may beapplied to the plates in any suitable way.

WVhat I claim is:

1. A marking device comprising a plurality of index members havingcircumferentially spaced characters and one thereof having a polygonalseat adapted to receive and hold the other member against rotation, anouter device cooperating with the said index members to produce theindication, and an axially located device serving to hold all the saidmembers together and in working position.

2. A marking device comprisin a shield having a sight opening andprovided with a polygonal pocket, of a polygonal index plate arranged tofit the pocket of said shield in various different positions and whichis provided with a polygonal pocket, a smaller polygonal index plateadapted to fit the polygonal seat of the larger index plate, indifferent positions, and an axially located device serving to hold thesaid index plates and shield interlocked and in working position,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDWARD A. CROSBY.
